SPEGIFIGATION formingpart of Letters Patent No. 728,858, dated May 26,1903.

i Application filed August 15, 1902. Serial No. 1191729- (N0 model-l Toall whont it may concern:

Be it known that I, EDGAR H. BYER, a citizen of the United States,residing at VVaynesboro, in the county of Franklin and State ofPennsylvania, have invented certain new and useful Improvements inVises; and I do hereby declare the following to be a full,clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to Vises used by jewelers and others who do finework; and it consists in the novel construction and combination of theparts hereinafter fully described and claimed.

In the drawings, Figure 1 is a side View of the vise. Fig. 2 is alongitudinal section through the vise, drawn to a larger scale. Fig. 3is a plan view. Fig. 4 is a front end view. Fig. 5 is a rear end view.Fig. 6 is a detail view of the collar and the nut for the vise-screw.

A is a supporting-base, which may be secured to any work bench or table,or it may be the work table or bench itself.

B is a circular base-plate secured to the base A and having a conicalbearing 17.

O is a forked bracket having a conical socket c, which is journaled onthe bearing 1).

Dis a center pin which is secured in the bracket 0 and which projectsthrough holes in the base-plate B and base A. A nut (Z is screwed on thelower end of the pin D and bears against a washer d on the under side ofthe base A. Then the nut d is tightened, the bracket is securely clampedto the baseplate.

The forked bracket 0 has guide-slots E in its sides. These slots arehorizontal for the greater portion of their length, and their front endsare curved downwardly and arranged in a Vertical position.

F is a block which rests on the bottom of the bracket 0 and which has ananvil-face f at its top. The block F is slidable longitudinally in thebracket C, and it is provided at its rear upper part with a pin G, theend portions of which form pivots which are slidable in the slots E.

The block F can be turned pivotally to any desired position irrespectiveof the position which is provided with a sleeve 2', which is journaledin a hole or bearing in the said block.

I is a collar which is secured to the end of the sleeve i by screws t"or in any other approved manner. The collar is arranged in the recess 9and bears against the face h, so thatthe jaw-head H cannot slidelongitudinally, but is normally free to revolve in the block F.

The collar I has an inwardly-projecting arm j, which carries a nutj forthe vise-screw to engage with. This nutj is arranged upon the axis ofthe sleeve 1'.

J is the outer jaw-head provided with a tubular bearingk, which isslidable longitudinally in the sleeve 2'. This tubular bearing has aslot is in one side, which engages with the arm j, so that the twojaw-heads always revolve together, and the nut j is supported inside thebearing 7;. The jaw-heads are provided with a plurality of opposed jawsof approved shape for holding a great variety of small objects.

M is the vise-screw, provided with a suitable handle for revolving, it.The vise-screw engages with the nut j and is journaled in the outerjaw-head J. A collar m is secured on the vise-screw inside the tubularbearing to prevent the vise-screw from sliding in the outer j aw-head.

The front edge of the bottom of the forked bracket is notched'or cutaway at s, so as to clear the tubular bearing 70 and the vise-screw Whenthe block is drawn forward and tilted up and the pivot-pin G is in thebottom ends of the vertical portions of the slots E.

Both jaw-heads are normally free to revolve, but when any object issecured between them the vise-jaws cause the inner jawhead to be pressedhard against the face h of the block. This clamps the jaw-heads, so thatthey cannot be revolved until the vise-screw is turned back, so as torelease the object.

A great variety of objects can be held between the vise-jaws in manydifferent positions, so that this device forms a very useful tool.

What I claim is- 1. In a vise, the combination, with a forkedsupporting-bracket having "l-shaped slots in its sides, of a tiltingblock slidable in the said bracket and provided with pivots which engagewith the said slots, means for clamping the said block to the saidbracket, and visejaws carried by the said block, substantially as setforth.

2. In avise, the combination, with a forked sn pporting-bracket havingslots in its sides, said slots having horizontal rear end portions anddownwardly-curved and vertical front end portions, of a block slidablein the said bracket and provided with pivots which engage with the saidslots, means for clam ping the said block to the said bracket, andvisejaws carried by the said block, substantially as set forth.

3. In a vise, the combination, with a forked supporting-bracket having'l-shaped slots in its sides, of a tilting block slidable in the saidbracket and provided with a pin at its upper rear portion which engagespivotally with the said slots, means for clamping the said block to thesaid bracket, and vise-jaws carried by the said block, substantially asset forth.

4. In a vise, the combination, with a bearing-block provided withparallel front and rear faces, and means for supporting the said block;of an inner jaw-head bearing against the said front face and providedwith a sleeve which is journaled in the said bearing-block, a collarsecured to the said sleeve and hearing against the said rear face andprovided with an inwardly-projecting arm and a nut, an outer jaw-headprovided with a tubular slotted bearing slidable in the said sleeve andengaging with the said arm, and a vise-screw journaled in the said outerjaw-head and engaging with the said nut and operating to clamp thejaw-heads to the said block, substantially as set forth.

5. In a vise, the combination, with a forked supporting-bracket havingslots in its sides, of a block slidable in the said bracket and providedwith a pin at its upper rear portion which engages pivotally with thesaid slots, an inner jaw-head provided with a sleeve which is journaledin the said block, means for preventing the said sleeve from slidingendwise, an outer jaw-head provided with a tubular bearing which slidesendwise in the said sleeve and passes under the said pin, a nutsupported from the said sleeve, and a visescrew journaled in the saidouter jaw-head and engaging with the said nut, substantially as setforth.

In testimony whereof I affix my signature in presence of two witnesses.

EDGARH. BYER.
